Firefighters from more than a dozen fire departments in the Upper Valley and beyond currently are fighting a four-alarm fire that broke out at a lumber mill off Interstate 89 on Wednesday night in Springfield, N.H.

The planer mill at Durgin and Crowell Lumber Co. danced with flames on Wednesday amid frigid cold temperatures that made the rescue effort considerably more difficult for crews on the scene.

Springfield Fire Chief Peter Lacaillade said firefighters were only able to attack the flames from the outside of the 210,000-square-foot building because there was an active fuel source inside. The scene was a flurry of activity as responders rotated out tankers and equipment to prevent them from freezing in the 6-degree weather. No injuries were reported, according to the Springfield department’s deputy chief.
